How do the new airport body scanners actually work?

Now listen here, you mullet. Why don't you just light your tampon, and blow your box apart? Because it's the only bang you're ever gonna get, sweetheart!

I dread to think where you're planning on hiding the bomb....

I was thinking more I would never be able to fly at certain times again coz I don't want strangers knowing private stuff. That would be embarassing.

But they do seem a bit pointless if a potential bomber has put something in an uncomfortable place.

What happens if you have a false limb. DO they make you take it off or are you supposed to tell them when booking?
